Electrical Data

The PFC-HF series of high frequency chip terminators are

available in standard chip resistor sizes. Available in 0402, 0603,

0805 and 1206 chip sizes, the PFC-HF is a drop-in replacement for poorer performing standard size chips.

With operation characterized to 6GHz, the PFC-HF series is suitable for RF and microwave transmission line

termination as well as high speed digital line termination. Applications include SCSI bus termination, DDR

memory termination, RF and microwave transmit and receive line terminations and general high speed trans-

mission line termination.
